Watching the video for the Kelvin Duo wireless wine thermometer put me in mind for a glass, so as I write this, I’ve a tasty little Sicilian red to hand. But how do I know that I’m getting the best from the wine? Let the wine breathe – check. Wide glass – check. Temperature….hmm, not so sure about that…and that’s where the Kelvin thermometer comes to the rescue.

The Kelvin Duo consists of a thermometer band that goes round the bottle, transmitting the temperature to a receiver which in turn shows the temp on a small screen. The screen’s backlight is colour-coded to red, green and blue for too warm, just right and too cold. The Kelvin is straightforward to use: first choose your wine, second select the category of wine from a choice of ten (four for white, three for red, two for sparkling and one for rosé), next put the band on the bottle and the bottle in the fridge. Finally, wait for the receiver screen to get into the green (or just flick into the blue) then pour and enjoy!

The Kelvin Duo is already on sale in the UK for £39.99 and will be coming to the US in the coming months with a price somewhere around $70-$80.
